CONTAINER FOR STORING PHOTOGRAJP'HIC PLATES.

Specification of Letters Patent. 1

Patented July '7, 1914.

Application filed February 18, 1914. Serial N o. 819,52 5.

To all whom it may concern Be it known that I, ERWIN MfiLLER- BRALITZ, a subject of the King of Prussia, and resident of Berlin-Wilmersdorf, Germany, have invented certain new and useful Improvements in Containers for Storing Photographic Plates, of which the following is a specification.

This invention relates to an improved container for storing photographic plates, which is to prevent the plates from breaking and from being damaged. This was hither; to not possible in an absolutely reliable way with the containers of known kind, which on their inner surfaces are provided with toothlike recesses in which the plates are inserted. This has the drawback that much room was lost in the interior of the container by the provision of the toothed racks. As the plates were arranged but loosely in these containers, they were thrown to and fro upon movement of the containers, particularly during transportation, whereby they were not only easily damaged but sometimes broken. To overcome this drawback, according to the present invention, the container is so constructed that it wholly or partly incloses with its inner surfaces all the four edges of the plates, which are pressed together by an arresting contrivance, so that the plates are supported upon each other and form thus a rigid glass body, which makes a breaking of the plates almost impossible. Furthermore, much room is saved by this arrangement. Between the single plates, a layer of paper or other suitable material is inserted, so as to prevent the negatives on the plates from being damaged, said insertions having preferably label-like projections, on which the nature of the negatives or the number of the plate may be marked.

The accompanying drawing shows the improved arrangement.

Figure 1 is a longitudinal section through the container, and Fig. 2 a cross-section on the line A-B of Fig. 1.

The container a is made of wood or other suitable material, and its dimensions are such that they suit the size of the plates to be stored.

b are the vertical side walls, and c the bottom of the container, which directly inclose three edges of the plates. The longitudinal upper edges of the side walls carry a tenon d, on which slides the cover 6.

0 is a longitudinal projecting ledge on the middle of the inside of the cover, which bears upon the fourth edge of the plates to be stored.

f, f are two boundary plates, which are placed in front of the inserted photographic plates and which are kept in place by wedges g, 9 which are clamped between the boundary plates and a rod h. The latter can be transversely inserted in the container in any position through a series of lateral holes 15 therein.

7c designates the label-like projections of the insertions between the plates.

I claim:

A container for storing photographic plates, comprising in combination, a threewalled casing adapted to inclose three edges of the plates tobe stored and having a series of holes in its side walls, a cover on top of the casing, a downward middle projection on the inside of the cover to bear upon the fourth edge of the plates to be stored, two loose plates in said container adapted to be placed in front of the photographic plates, a loose rod transversely inserted in any position through said holes, and wedges to be clamped between said rod and said boundary plates to keep the latter in place upon the plates being inserted, substantially as and for the purpose set forth.

. In testimony whereof I have hereunto set my hand in the presence of two subscribing" witnesses.
